To all whom t l Be it known that I, HUGo REICHEL, a citizen of theUnited States, residing at Chicago, in the county of Cook and State ofIllinois, have invented a. certainy new and Other objects will appearfrom time to time cutters.

in the course of the specification and claims.

I illustrate my inventioumore or less diagrammatically in the`accompanying drawings wherein Figure 1 is a side elevation of my devicewith parts in section; v A

Figure 2 isl a partial plan view; and

Figure 3 is a section through a varlant form.

Like parts are illustrated b likel charf acters throughout the specication and drawings. A

A is any suitable frame supported on a base A1.

B, B are feedin a roll or strip o rial B1. l

C is any suitable supporting table over which the strip 'of materialpasses, and which serves rto align the strip with the rollers adapted tofeed shingle forming mate- D is a cutter shaft mounted in any suitablebearings D1 on the frame A.

E is a second cutter shaft mounted in any suitable bearings E1 on Vtheframe A. l It is driven from a power source notherein shown, through thepulley E2 on the pulley shaft E"1 and the pinion Es and the gear E onthe shaft E. While I do not limit myself 45 to the specic driving meansherein described, and illustrated, I find it satisfactory thus to drivethe shaft E and to drive the shaft D from the shaft E by means of thegears E6 and' D2 which are of the same diameter. The feed rolls may bedriven from the shaft D by means of the gear D2, the idler D3 and thegear D1.

Each cutter shaft is provided with two cutting edges respectivelyindicated as D10, D12 and E10, E12, it being understood that D10 and E1oareA complementary,l while D12 and E12 lare complementary, the twocompairs differing from each other.

plementar lvuafts D and E rotate at the same The Y'two s rate, but itwill benoted that the cutting4 edges E1", E12 are illustrated assubstantially farther from the center of the shaft E than are ythecutting ed es D10, D12 from the center. of the shaft Therefore, whileD1, E1o and D12, E12 meet at thesame point on each revolution, they passthat point at different speeds, E1o or E12 moving suiliciently fasterthan D1o or D12 toshear oft' any material which may be interposedbetween them. The said rollers are geared to feed a length( of materialat each half revolution of the cutting shafts just suf'lcient to form aunit of article vbeing produced.

In Figure 3 I yillustrate a variant device in which a slide I-I actuatedby the-link H1 from the crank H2 'is pushed forward to meet the cuttinged e E1, whereas a second slide J actuated, link J 1, is pushed forward,tol meet the cutedge E12, I-I being meanwhile drawn out of position,the two slidesl bein reciprocated -in synchronized relation witv therotation of the shaft E. A

It will be realized that'while I have i1- lustrated a working device,and one which is actuallyl bein operated commercially, I do not wlsh to1t myself to the specific y:form being herein shown. lMany changes mightbe made in the size, shape,` number an disposition of parts withoutdeparting from the spirit of my invention.

The use and are as follows:

In shingling roofs with shingles cut from the various compositions nowused for shingle manufacture, it is often advantageous to employshingles'of irregular shape, for

operation fof my invention example, for forming interlocking shinglesIorhy example through a the shingle or other herein illustrated, I show arotary cutter having two diametrically opposed cutting blades ofdifferent contour. Since as the cutter is rotated, the blades alternate,the objects cut will be given the impression of one blade on one sideand one blade on the other. When my cutter is used to cut shingles wherethe opposed sides are complementary, namely, where the left side of oneshingle fits into the right side of the next, I form the shingles byemploying a cutter wi'thcomplementary blades. As the cutter is rotated,one blade forms the second side of the completed shingle and at the sametime shears it off and forms the first side of the succeeding shingle.There is, therefore, no loss of material. As the above described rotarycutter, which I may call the primary cutter, rotates it, must havepresented to it secondary cutter blades or bases. In the form hereinshown E is the primary cutter shaft and the blades E1", E12 are theprimary blades. To them as they pass the cutting point I oppose thesecondary cutting blades or bases which in Figure 1 are shown as therotary blades D, DI? and in Figure 3 are shown as the reciprocatingslides H and J. Where. I use a rotary cutter, it will be understood thatthe secondary cutter blades or bases must move very substantially slowerthan the primary blades and I get this result by very substantiallyreducing the distance of the secondary blades from their center ofrotation as compared to the distance of the primary blades from theircenter of rotation. I then rotate both shafts at the same speed and aseach opposed pair. of cutters meet, the primary cutter is travelling somuch faster than the secondary cutter that.

any materialinterposed between them is sheared olf.

It will .of course be understood that while I have described the use ofmy device for use with shingles, that I do not` wish to be limited tosuch use and with minor changes in design and any desired variation insize my device ,may be adapted to a wide variety of objects Where it isdesired to cut off portions of a strip of material to form units havingdifferently formed sides.

Also, while I have described my device as used for shearing shingleswhere the opposed sides of the shingle are complemen- Itary,'it may beused to shear off sections in which. the opposite sides are notcomplementary, being entirely different. In that case each finishedarticle is separated from the .next by a blank of'the waste material. Mydevice can of course -be used for cut ting straight sided' objects, ifso desired.

I claim:

In a device for cutting from a relatively continuous strip ofmaterial articles having opposed edges of different contour, a feedingmeans for feeding said material forward, a rotary cuttingbase overwhichsuch material passes, said cutting base bei ing provided with aplurality of cutting blocks of different contour, a rotary knifeadjacent said rotary base, a plurality of cutting edges upon said knifeshaped to conform to said cutting blocks, and means for rotating saidknife and said base in opposite directions of rotation, tobring thecorresponding cutting bases and cutting edges into opposition at apredetermined point, the radius of said cutting edges bein substantiallygreater than the radius o said cutting blocks.
